Drain control means



Feb.v 12, 1935. B. GRISMER I DRAIN CONTROL MEANS Filed Dec. 5, 1933 Patented Feb. Y 1 1 935 UNITE i STAT-Es rrfrsirr OFFICE This invention relates to drain control means for vthe suction pipe or line of a pump, and it is an object of the invention to provide a means of this kind which can be readily applied to and eiectively employed'with a suction pipe or line pipe or line at apoint below thefreezing point,

the movement of the valve member in opposite directions being limited to assuresaid member at all times overlying the drain opening or vent so that saidrmember provides an eifective medium to prevent the water as it drains out through the opening Vor vent being discharged upon or squirting against the well casing and washing off rust on the casing down into the water thus not only eliminating such contamination of the water but materially prolonging the life of the well casing. i

Another object of the invention is .to provide a means for controlling the discharge through a drain opening or vent provided in the wall of a suction pipe or line for a pump including ay sliding valve member for saidpump which -is moved downwardly when it is desired to open the flow out through the drain opening or vent and wherein said valve member carries a. facing of leather or kindred material which constitutes the valve member for closing the drain opening or vent when the valve member is moved upwardly, the' r downward movement of the valve member to open the drain opening or vent positioning the facing below the opening soythat the water as discharged through the drain opening or vent will wash down A over the facing and thus prevent the same from drying out randl in the course of time becoming defective assuch mo-isteningof the facing will maintain the same wet and soft so that it will have proper coaction with the pipe or line.

The invention consists in the details of conu struction and in the combination and arrangement of the several parts of my improved drain control means for the suction pipe or line of a pump whereby certain important advantages are attained and the device rendered simpler, less 0 expensive and otherwise more convenient and advantageous for use, aswill be hereinafter more `muy ser forth.

Figure 6 is a fragmentary View partly in *sectionV andpartly in elevation illustrating in detail the 20' means herein employed for mounting the pipe protector.

As disclosed in the accompanying drawing, P denotes a conventional type of pump mounted upon a wall head Hand which pump has depending therefrom a suction pipe or line L adapted to extend a required distance within a wellopening and more particularly within a wellv casing (not shown). The line L at 'a desired distancebelow the pump P is provided'in its wall with a drain opening or vent 1. This opening or vent V,1 is positionedV a distance below the pump P Vsufficient to be arranged below the freezing point and is, of course, provided to allow water within the line L within the freezing Zone to readily drain out.

The foregoing features referred to are well known and form no part of Vthe present invention.

My improvedY means for controllingithe vflow through the opening or vent l, as herein disclosed, comprises two elongated guide strips 2 adapted tobe arranged in parallelism upon the-pipe or line L at opposite sides of the opening or vent l. Riveted, as at 3,` or otherwise` attached to the inner faces of the strips 2 are the laminations'i through as particularly illustrated in Figure 5 55T so that the 'nut 8 can 'be employed to effect the desired clamping of the members 2 upon the pipe or line L. Y Each of the straps 6 at a desired point thereon is provided with an opening 9 adapted to register 60 with an opening 10 provided in the wall of the pipe or line L so that a screw 11 may be employed for further holding the strips 2 in applied position. Y

The screws 11 are preferably employed when the pipe or line L is of a size to be inserted within a casing approximately three inches in diameter and when so used and if necessary, after the screws 11 have been applied the bolt 7 may beV removed and the extended ends ofthe straps 6 bent as by hammer blows to lie close adjacent the periphery of the pipe or line L.

Freely slidable between the strips 2 is an elongated valve member M which passes between the pipe or line L and the portions of the bands 5 bridging the space between the strips 2 and riveted, as at .12, or otherwise carried by the member M at a point between Vthe bands 5 is a Ystop block or part 14 which is adapted to contact with the bands 5 whereby the extent of endwise movement of the member M in either direction is positively limited.

The inner face of the valve member M at the lower end portion thereof has riveted, as at 15, or otherwise secured thereto a facing 16 of leather or kindred material and which constitutes a valve having direct contact with the periphery of the pipe or line L and which facing or valve 16 when the member M is in its raised or lifted position closes the drain opening or vent 1. The upper portion of this facing 16, as indicated by broken lines at 17 in Figure 2, is gradually reduced in width and as illustrated in Figures 3 and 4 this upper restricted end portion of the facing 16 is beveled upwardly and outwardly toward the member M, as indicated at 18. This restricted portion 17 of the facing 16 together with the bevel 18, when the member M is in its lower position, assure the desired opening of the vent l with the desired discharge of the Water therethrough from within the pipe or line L.

As is illustrated in the accompanying drawing, the'lower band 5 iskso positioned upon the pipe or line L to limit further downward movement of the member M shortly after the lamination 16 has been shifted substantially entirely below the drain opening orA vent 1. With the member M in open position as illustrated in Figure 4, the water as it discharges through the opening or vent 1 will contact with the overlying portion of the member M and thus be prevented from squirting upon the well casing and carrying down into the water rust which may have accumulated on the inner surface of the casing. A continued action of this kind within a reasonable time would result in a material deterioration of the casing aside from a pollution of the water. Therefore, my improved control means materially prolongs the life of the well casing.

It is also to be particularly noted that when the drain opening or vent 1 is open for discharge therethrough, the member M is in a position to arrange the facing 16 below said opening or vent 1 so that the water as it discharges through such opening or vent 1 will effectively wash over the facing 16 and thereby maintain the same moist and soft so that it` will be in the best possible condition for effective use and not allowed to dry out. The discharge of the water through the opening or vent 1 is further facilitated by the restricted portion 17 and bevel 18 at the upper part of the facing 16.

An elongated operating member 19 is secured at its lower end to the upper portion of the member M and this operating member 19 is of a length to extend a desired distance above the well head so that a person upon the ground level may readily adjust as desired the member M into open or closed position with respect to the drain opening or' vent 1.

This operating member 19 as herein disclosed is directed through an elongated pipe or tubular member 20 which protects the major portion of said member 19 above the head H or above the ground surface from being in any Way retarded in operation by freezing. The lower portion of this member or pipe 20 as herein disclosed is directed through a suitably positioned opening in the base flange 21 of the pump P and has threaded thereon above and below said flange 21 the holding nuts 22. Positioned between the uppermost nut 22 and the flange 2l is a washer 23 of rubber or similar material and interposed between this washer 23 and the uppermost nut 22 is a metallic washer 24. The nuts 22 and the parts associated therewith provide an effective means for maintaining the pipe or tubular member 21 in Working position.

From the foregoing description it is Vthought to be obvious that a drain control means constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modication without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:-

In combination with the suction pipe line of a pump, the Wall of which has a drain opening, elongated strips disposed lengthwise along the pipe line at opposite sides of the drain opening, bands secured to said strips and bridging the space therebetween, means associated with said bands for holding the strips to the pipe line, an elongated valve member engaged between the strips for sliding movement lengthwise of the pipe line, said valve member being held in place by the portions of the bands bridging the space between the strips, a stop member carried by the valve member between the bands for contact with the bands to limit the movement of the valve member in opposite directions, and a leather' facing carried by the inner face of the valve member, said leather facing closing the valve opening when the valve member is raised, said leather facing being entirely below the drain opening when the valve member is in its lowermost position., the portion of the valve member immediately adjacent to the leather facing serving to direct the water passing out through the drain opening upon the leather facing, the upper end portion of the facing being beveled, said bevel facilitating draining of the pipe line when the valve member is 'm its lowered open position.
